One question (sorry if someone already asked, I scanned the thread but it is getting long..):Taking this example from the RFC: function g($p = null) { f($p ?? default); }Could you go one step further and use default by default but still allow null to be passed in?function g($p = default) { f($p); }I suppose this would mean $p has to hold this "default" value until a function call is reached, at which point it would resolve to whatever the default is. This probably complicates things for very little gain but I had to ask.
First, it would be some sort of spooky action at a distance, likely add a new zval type etc.; lots of special handling for a likely minor benefit.
Second, I'd expect that bit of syntax do be useful in inheritance - like you implement or override a parent class/interface method specifying a default; then you can just use the default of the parent method.
